| Research Abstract |
The timing of critical period of ocular dominance plasticity in mice are regulated with cortical inhibitory circuit development. In this study we have tested whether this principle can be applied to the critical period in bird song learning. Early GABA enhancement in the developmental birds brain disrupted later song learning in male zebra finches by closing sensory learning period earlier. Here we suggested conserved critical period mechanism, inhibitory circuit control of critical period.
